I am trying to get this feature to work in my environment, but I can
not for the life of me figure it out. I have two ovs' sitting on
two separate boxes connected through an external switch. I have
updated each bridge port to be native-untagged and updated the tag
with the vlan as well. I have updated the trunk port egressing out
of each ovs to the external switch. I have configured the external
switch to tag all vlans except the vlan in question. I can see the
changes to the bridge ports working as configured, when I tcpdump on
the vm I see the packet untagged, when I tcpdump on the bridges,
both fake and real, I see the packet untagged. I can not tcpdump on
the trunk port, but I can on the individual ethx interfaces, that's
where I see the packet tagged. So before it leaves my box it is
tagged. Is native-untagged supposed to work with bonds? Thanks,
Native-untagged should work on bonds.
Your description of the tcpdump output doesn't help much. You don't
say whether the packet in question is in the native VLAN, so, while
you tell us at each point whether the tag is there, we don't know
whether it's supposed to be there.
Cool. The packet, in this case an ARP broadcast, is generated on a VM
that is configured as an access port in vlan 102. I have configured the
port using the following:
ovs-vsctl add-port DevNet102 vifXX.0
I have verified that vlan_mode is not set and tag is set to 102. I
created the fake bridge as follows:
ovs-vsctl add-br DevNet102 DevNet0 102
I have verified that vlan_mode is set to native-untagged and tag is set
to 102. I created the real bridge as follows:
ovs-vsctl add-br DevNet0
I have verified that vlan_mode is set to native-untagged and tag is set
to 102. I created the bond as follows:
ovs-vsctl add-bond DevNet0 bond0 eth0 eth1 eth2 eth3
I then used the following to change settings for the bond:
ovs-vsctl set Port bond0 lacp=active
ovs-vsctl set Port bond0 bond_mode=balance-tcp
ovs-vsctl set Port bond0 vlan_mode=native-untagged
ovs-vsctl set Port bond0 tag=102
I have verified that vlan_mode is set to native-untagged and tag is set
to 102. I have also verified that LACP is working with the external
switch.
I have configured the external switch with it's default-vlan as 102 and
untagged each port of the bond into vlan 102.
All interfaces are up and passing traffic. Again, I can see the
packets untagged using tcpdump on each bridge port and inside the vm,
but when I start dumping on the individual OS interfaces, eth0, eth1,
etc, of the bond I suddenly see that the packet is tagged.
When I capture on DevNet0, I am seeing packets coming from ovs into the
port, right? That would be packets egressing from ovs, correct?
